Celtic iron plain brooch

The Celts were a diverse group of tribal societies in Iron Age and Roman-era Europe who spoke Celtic languages. The earliest archaeological culture commonly accepted as Celtic, or rather Proto-Celtic, was the central European Hallstatt culture (c. 800-450 BC), named for the rich grave finds in Hallstatt, Austria. By the later La Tène period (c. 450 BC up to the Roman conquest), this Celtic culture had expanded over a wide range of regions, whether by diffusion or migration: to the British Isles (Insular Celts), the Iberian Peninsula (Celtiberians, Celtici and Gallaeci), much of Central Europe, (Gauls) and following the Gallic invasion of the Balkans in 279 BC as far east as central Anatolia (Galatians).
